1 Claim.

This invention appertains to tobacco users appliances, and moreparticularly to a novel smoking pipe.

One of the salient objects of our invention is to provide a smoking pipein which the smoke is cooled prior to entrance of the same in the usersmouth, and in which moisture, residue, etc., is confined in the stem andagainst admittance in the mouth with the smoke.

Another important object of our invention is to provide a smoking pipeof the above character, which can be readily and quickly taken apart topermit the thorough and expeditious cleaning thereof, whereby the pipecan be conveniently 15 kept in a sanitary condition and the smokepassages kept clean for full passage of the smoke.

A further object of our invention is to provide a smoking pipe, in whichthe entire stem and bit is divided longitudinally, whereby the sectionsof the stem can be separated to expose the smoke passageways to view, sothat the same can be readily cleaned, the sections of the stem beingpreferably united by a tongue and groove to permit the sections to beconveniently and quickly united, and whereby a substantially leak-proofjoint will be had.

A further object of our invention is the provision of a mating taperedtongue and groove formed on the meeting faces of the stem sec- -tions,so that the sections can be effectively wedge-d together to form thedesired tight joint, the lower section having a strike portion formedthereon, normally projecting beyond the bowl, so that said portion canbe struck to facilitate the initial movement of the lower section whenit is desired to take the sections apart.

A further object of our invention is to provide a smoke pipe in whichthe entire stem and bit are divided longitudinally and united by atapered tongue and groove, one section being provided with a tortuous orcircuitous passageway opening out through one end of the stem, andcommunicating at its opposite end with a passageway formed in the bowland opening out through the other section of the stem.

A still further object of our invention is to provide a smoke pipe ofthe above character, which will be durable and efiicient in use, onethat will be simple and easy to manufacture, and one which can be placedupon the market at a reasonable cost.

With these and other objects in view, the invention consists in thenovel construction, arrangement and formation of parts, as will behereinafter more specifically described, claimed,

and illustrated in the accompanying drawing in which drawing:

Figure 1 is a longitudinal section through a smoking pipe, constructedin accordance with my invention;

Figure 2 is a bottom plan view of our improved pipe with the lowersection of the stem removed;

Figure 3 is an enlarged detail end view of the upper stem section;

Figure 4 is a top plan view of the lower stem section removed from thepipe;

Figure 5 is an enlarged detail end view of the bottom stem section;

Figure 6 is a detail transverse section through the pipe taken on theline 6-6 of Figure 1, looking in the direction of the arrows.

Referring to the drawing in detail, wherein similar reference charactersdesignate corresponding parts throughout the several views, the letter Agenerally indicates our improved pipe, which comprises the bowl I0 andthe stem II. The bit I2, as shown, is integrally connected with thestem. If preferred, the bowl and stem can be made integral and formedout of briar or similar hard wood, or the bowl can be made separate fromthe stem and detachably connected therewith. In such case, the stem canbe formed from hard rubber or Bakelite, and the bowl can be formed fromwood.

In the drawing, the bowl I0 has been shown formed separate from thestem, and its connection with the stem will be later described.

In accordance with our invention we divide the stem II longitudinally toprovide an upper section I3 and a lower section I4. The sections I3 andI4 are detachably connected together by a mating tongue and groove. Forthe purpose of illustration, a dovetailed groove I5 is formed in thelower face of the upper section I3, and a dovetailed tongue I6 is formedon the lower section I4. The groove I5 and the tongue I6 are taperedtoward the bowl end of the pipe so that when the sections are slidtogether, a wedging effect will be had to provide a tight joint. Thelower pipe section I4 is provided with an outwardly projecting strikeportion II which normally projects beyond the bowl I I] and the upperstem section I3 when the stem sections are united, and this portion IIforms means for facilitating the striking of the lower stem section onan object to permit the initial loosening thereof, so that said lowerstem section can be readily slid oil of the upper stem section.

The forward end of the upper stem section I3 is provided with a cavityor socket I8, and the removable bowl H) has its lower face rabbeted toprovide a flange IQ for reception in said socket. This forms a frictionjoint for uniting the bowl with the stem. A forwardly and laterallyextending smoke passageway 28 is formed in the upper stem section andcommunicates with the cavity or socket 18 at one end and opens outthrough the lower face of the groove at its opposite end.

To form means for cooling the smoke as the same is drawn through thestem and to prevent the drawing of moisture, tobacco residue, etc., inthe mouth with the smoke, the lower section 4 of the stem has its innerface provided with a tortuous or circuitous passageway. This circuitouspassageway defines side longitudinal passageways 2i and 22, and anintermediate longitudinal extending passageway 23. The forward end ofthe longitudinal passageway 25 communicates with a cavity 24 which isadapted to register with the smoke passageway 20 formed in the upperstem section l3 when the stem sections are united.

The other side longitudinal passageway 22 communicates at its out endwith a smoke passageway or outlet 25 formed in the bit end [2 of thestem. The opposite ends of the intermediate longitudinal passageway 23communicate with the opposite ends of the side longitudinal passageways2! and 22. When the stem sections are united the inner wall of groove 15closes the tops of the passageways and prevents leakage of smoketherefrom, but obviously a cork gasket, or the like, can be placedaround the circuitous passageway to prevent leakage.

In use of our improved pipe, the bowl is filled with tobacco in theordinary way, and when the user draws on the pipe the smoke will bedrawn down through the passageway 20 into the cavity 24 through thepassageways 2|, 23, 22, and out the passageway 25. Obviously, during thetravel of the smoke through the passageways the same will be effectivelycooled, and

the ends of the passageways will tend to prevent moisture and the likefrom entering the mouth of the user.

When it is necessary to clean the pipe, the strike portion I! is tappedon an object, which loosens the sections, and the sections are then slidapart. Obviously, this exposes all of the passageways to view, and thusthese passageways can be expeditiously cleaned and kept in a sanitarycondition.

The pipe sections are united by simply sliding the tongue into thegroove. If preferred, the forward end of the section [4 can carry a stoplug 23 for fitting in a groove 21 in the top stem section I3. This willprevent the bottom section from being slid too far into the top section.

From the foregoing description, it can be seen that we have provided anexceptionally simple and durable pipe which will effectively cool thesmoke, and which can be kept in a sanitary or clean condition.

Changes in details may be made Without departing from the spirit or thescope of our invention, but what we claim as new is:

A smoke pipe comprising a bowl and a stem having a bit, the stemincluding a pair of longitudinally extending companion sections, thesections being provided with a mating tongue and groove, the tongue andgroove tapering toward the bowl end of the pipe, one of said sectionshaving a smoke passageway therein communicating with the bowl, the otherof said stem sections having a circuitous passageway opening out throughthe bit end of the stem and communicating with the first mentioned smokepassageway when the sections are united, and a strike portion formed onthe forward end of the lower stem section normally projecting beyond thebowl whereby to facilitate the initial displacement of the sections whenthe same are to be separated.
